I guarantee they don't know anything about hillary's email other than some highly inaccurate memes they've seen shared on facebook. Doubt they even knew about the 'sniper fire' bullsh*t or have heard anything about 'missing billing records'. I guarantee they can't say WHY they hate her. They just do, because they've been told she is bad.
My wife's 85 year old grandfather (who lives in Florida) voted for Obama at least once, maybe twice, but now he doesn't like him and he says his worst fear is Hillary will be like an Obama 3rd term. Why? He went from voting for Obama and he saying he thinks he is doing the best he can with Republicans obstructing everything he tries to do to having Hillary being a 3rd Obama term as the big fear that could keep him from voting for her. He thinks Trump "might be okay domestically but would be a disaster for international relations". I think he might actually pull the lever for Hillary in the end, but the fact that he is even conflicted about this blows my mind considering I used to consider him a reasonable guy politically -- could vote R or D but didn't like anyone too extreme on either end (but kind of a fossil when it came to social things like same sex marriage, but in the end didn't really give that much of a **** about it and wouldn't let a candidate's stance on that affect his vote). His youngest son reenlisted in the Army 9 years ago or so (he had done some time out of high school during the first Gulf War, but then left the military for a while), and I've seen him go from a reasonably moderate guy that used to talk about Austin, TX as an "oasis of liberalism" (like it was a good thing) when he was stationed in Texas to a guy that openly bashes Obama on Facebook (despite being active military). I'm pretty sure he's the one that convinced his father that Obama is a bad president. Trump could murder a child on live TV and Hillary could cure cancer, and I'm pretty sure he would still hate Hillary.
